There's 2 different types of delegates in WV, county delegates and national delegates. The county delegates are elected to go to the state convention to vote on which candidate gets to pick the national delegates to go to the RNC national convention. The national delegates are won at the state convention, but in order to win we have to have people running as county delegates so Paul has a voice.
Theoretically, the candidate with the most county delegates going to the state convention will win the state convention and in turn send their delegates to the national convention. This year, the majority of county delegates so far are uncommitted, meaning they don't have a presidential preference. This state convention could be a big drop down drag out fight for the national delegates.
